Katherine Heigl on a Mission to Save Dogs

Katherine Heigl is on a mission. The “Grey’s Anatomy” actress has teamed up with Best Friends Animal Society’s Pup My Ride, an animal rescue program that transports shelter dogs in danger of being put down to new, out-of-state homes.

“Over 600 dogs have been saved and adopted,” Heigl told “Access Hollywood.”

“Up in Utah and Arizona and some of these states around California, they have waiting lists for small dogs, people wanting to adopt and here [in Los Angeles] we have an overwhelming number in the shelters,” Heigl said.

“Today is the transport day,” Heigl said. “I think [the dogs] are either excited or terrified. I’m not sure.”

Heigl owns six rescue dogs with her husband, Josh Kelley.

“I think my husband’s ready to kill me,” Heigl said. “But you know what? The last [dog] was his idea.”

Kelley found their sixth dog in a trashcan in Mexico when he and Heigl were there on vacation a year ago.

“Someone had literally thrown him out, and he was probably at the time, three or four weeks old,” she said. “He was just this teeny, tiny, fit-in-the-palm-of-my-hand, and Josh said, ‘I think we should take this one home,’ and I said, ‘OK! I’m dying for a puppy.’ But now I can blame him for it, too. I’ll be like, ‘This puppy was your idea. You get up with him at 7!’ ”
